As Anderson et al. noted in 2013, one of the many applications of computer games is digital game-based learning. Corresponding approaches include game-based learning in computer science or computer-supported or -based serious gaming, as often seen in wargaming. Yet, since traditional software development approaches tend to require technical skills and expertise in the field of programming and are characterised by inflexible development processes that make digital game delivery quite resource intensive, they pose a significant obstacle to non-technical game designers interested in digital games. 3 As a result, in the past a developer was often needed to facilitate the creation of computer-supported or computer-based games.
